Network node, user equipment and methods for handling signal quality variations

Abstract

Embodiments herein relate to a method performed by a network node (110) for handling signal quality variations for UE (120). The network node (110) predicts a future signal quality variation indicative of a path of movement for second UE (120b) being served by the network node (110). The predicting is based on historical data of previous signal quality variations for one or more first UE (120a) having been served by the network node (110). The historical data of previous signal quality variations is indicative of a path of movement of the one or more first UE (120a). The network node (110) determines to change a network configuration for the second UE (120b) based on the predicted signal quality variation. The network node (110) initiates the change of the network configuration for the second UE (120b). Embodiments herein further relate to a method performed by UE (120a, 120b) for handling signal quality variations for the UE (120a, 120b).

Description

technical field [0001] Embodiments herein relate to a network node, user equipment (UE) and methods performed therein. In particular, they relate to predicting signal quality variations of UEs in a wireless communication network. Background technique [0002] In a typical wireless communication network, a wireless device (also referred to as wireless communication device, mobile station, station (STA) and / or user equipment (UE)) communicates with a or multiple Core Network (CN) communications. The RAN covers a geographical area divided into service areas or cell areas (they may also be referred to as beams or beam groups), where each service area or cell area is served by a radio network node such as a radio access node, e.g. A Wi-Fi access point or radio base station (RBS), which in some networks may also be denoted as a NodeB, eNodeB (eNB) or, in fifth generation (5G), gNB. A service area or cell area is a geographical area where radio coverage is provided by a radio ne...

However, when operating at higher frequencies in NR, such as for example above 28 GHz, shadowing and penetration losses will increase because higher frequencies

This can lead to very rapid signal drops, for example when the UE is operating in an urban environment (e.g. in a city) and loses line of sight to the base station, for example when the UE turns a corner and a building or obstacle blocks access from the UE When the direct radio path to the serving base station
